Mounting Plate RAM Mounts RAMB202U — aluminium round plate with 1" ball, black

RAM Mounts RAMB202U is an aluminium round mounting plate with an integrated 1" rubber ball, finished in black. The compact design combines a 2.5" diameter flat base with a resilient 1" ball that serves as a stable pivot point for RAM arm systems and compatible cradles. Pre-drilled holes include a universal AMPs hole pattern, enabling secure attachment to flat surfaces in marine, vehicle, industrial, and DIY installations where a low-profile, durable mounting base is required.

Advantages

The aluminium construction provides corrosion-resistant strength while keeping weight low, and the black finish offers a discreet appearance. The integrated 1" rubber ball ensures vibration dampening and flexible positioning when paired with RAM double-socket arms or cradle assemblies. Pre-drilled mounting holes, including the AMPs pattern, simplify installation and offer compatibility with a wide range of accessories and mounting hardware.

Suitable for

• Mounting electronic devices and cradles in boats and marine applications
• Fixed or removable mounts in cars, trucks, and utility vehicles
• Industrial or workshop equipment that requires a compact pivoting base
• DIY projects and custom installations where a robust, low-profile mount is needed

Key specifications

• Material: aluminium base with a rubber 1" diameter ball
• Base diameter: approximately 2.5" (flat round plate)
• Finish: black
• Mounting: pre-drilled holes including the AMPs hole pattern for wide accessory compatibility
• Function: provides a pivoting connection point for double-socket arms and device cradles

How to use

Position the plate on a flat, rigid surface and mark hole locations using the pre-drilled pattern as a template. Select appropriate fasteners for the mounting surface material and tighten securely through the plate holes. Attach a compatible RAM arm or cradle to the 1" rubber ball by clamping with a double-socket arm or ball clamp, then adjust the device to the desired angle and torque the arm clamp to lock the position. Periodically check fasteners and clamp tightness, especially in high-vibration environments.

Usage recommendations

Use corrosion-resistant fasteners for marine or outdoor installations, and follow recommended torque settings for RAM arms to avoid over-tightening the rubber ball clamp. For exposed installations, inspect seals and mounting points regularly and replace worn components to maintain a secure, vibration-damped connection.
